Baffle leak following lateral tunnel Fontan--treated with a vascular plug.

Various devices have been used for the percutaneous closure of fenestration and baffle leak associated with Fontan operation. We describe a 14-year-old male who had presented with increasing cyanosis and effort limitation following lateral tunnel Fontan operation. Apart from a fenestration in the lateral tunnel, there was an unusual baffle leak leading to significant right-to-left shunt. Following a test occlusion of the leak, an Amplatzer vascular plug was successfully used to occlude it, which resulted in significant improvement in systemic oxygen saturation. The advantages and disadvantages of Amplater vascular plug for the closure of baffle leak are discussed.
